Garland, TX Electrical Panel & Service Upgrade Guide

Estimated Read Time: 9 minutes

If you are planning to upgrade from 100 amp to 200 amp service, you are likely adding big draws like EV charging, a heat pump, or a kitchen remodel. This guide explains when a 200 amp upgrade makes sense, how it works in Dallas–Fort Worth, and what it costs. We also cover permits, utility coordination, and safety steps so you can plan with confidence and avoid surprises.

Do You Need a 200 Amp Service Upgrade?

A 100 amp service can power many older homes, but it is often tight once you add modern loads. Signs you need more capacity include frequent breaker trips, lights dimming when the A/C starts, or an electrical inspection that shows limited panel space.

Consider a 200 amp upgrade if you plan any of the following:

1. Level 2 EV charging or multiple EVs.
2. Heat pump or larger HVAC equipment.
3. Induction range, double ovens, or a full kitchen remodel.
4. Hot tub, sauna, or pool equipment.
5. Detached shop with tools or a future accessory dwelling.

A 200 amp main gives headroom for growth and reduces nuisance trips caused by stacked high‑demand appliances. It also creates room for new dedicated circuits, AFCI and GFCI protection, and whole‑home surge protection.

What Changes When You Upgrade From 100 Amp to 200 Amp

A service upgrade is more than swapping a breaker. It is a coordinated change from the utility connection to your distribution panel.

Key components typically updated:

1. Service entrance conductors sized for 200 amps, often 4/0 aluminum or 2/0 copper, based on code, distance, and conditions.
2. Meter base rated for 200 amps.
3. Main breaker panel rated for 200 amps with enough spaces for present and future circuits.
4. Grounding electrode system improvements, such as bonding and ground rods, per current code.
5. Whole‑home surge protection at the service equipment. The 2020 National Electrical Code requires a surge protective device at dwelling unit services. See NEC 230.67.

The result is a safer distribution system that can handle larger continuous and non‑continuous loads without stressing equipment.

Safety, Code, and Permits You Should Know

Electrical service equipment must meet the current code adopted by your city and utility. Two facts help homeowners plan:

1. NEC 230.67 requires a Type 1 or Type 2 surge protective device at the service for dwelling units in codes adopted since 2020. We install SPDs at the panel during upgrades.
2. Continuous loads are calculated at 125% for conductor and device sizing. This is why houses that never “pull” a full 200 amps still benefit from a 200 amp rating and correct load calculations.

Expect these compliance steps:

• Permit application with your city.
• Utility coordination for meter pull and reconnect. In DFW we commonly coordinate with Oncor for safe disconnect and tagging.
• Inspection by the authority having jurisdiction before re‑energizing. We schedule and meet the inspector.

Our team documents the work with photos, torque records where required, and a final checklist so you know everything was done to spec.

The Step-by-Step Process We Follow in DFW

Here is how a typical upgrade goes with our team.

1. Load evaluation and panel inspection
   • We review existing circuits, open the panel, and look for heat signatures with thermal imaging. Hot spots point to loose lugs, failing breakers, or mis‑sized conductors.
   • You receive a risk‑coded report with green, yellow, and red findings, plus recommendations.
2. Proposal and options
   • We present good, better, best. Options can include a panel relocation to meet clearance rules, surge protection, and capacity for an EV charger or future solar backfeed.
3. Permitting and utility scheduling
   • We file the permit, then coordinate the outage window with Oncor or your utility. You get exact dates and timelines.
4. Upgrade day
   • Power is safely shut off. We replace the meter base, service conductors, main breaker panel, and grounding as needed. We label circuits and correct any unsafe wiring we find.
   • We keep the work area clean and wear shoe covers inside your home.
5. Inspection and power restore
   • City inspection is completed. After approval, the utility reconnects service and we verify correct voltages, phase presence, and breaker operation.
6. Final walkthrough and documentation
   • We show you the new panel layout, surge protection indicator, and any maintenance tips. Your invoice and photos are emailed, and members get their 15% discount.

Most upgrades complete in one working day. Complex relocations, long service runs, or masonry work can add time.

Cost Factors and Ways to Save

Every home is different. These items influence the final price:

1. Panel location and clearance. A relocation from inside to outside adds labor and materials, but may be required by code or for access.
2. Service entrance length. Longer conductor runs or mast work increase cost.
3. Meter base and utility requirements. Some utilities require specific meter cans or riser hardware.
4. Grounding and bonding corrections. Older homes often need upgrades to meet today’s rules.
5. Add‑ons. Whole‑home surge protection, AFCI and GFCI upgrades, new dedicated circuits, and EV chargers.

Ways to save without cutting corners:

• Bundle projects. Do the 200 amp upgrade with your EV charger or kitchen circuits to reduce repeat trips and permits.
• Use our membership plan. Members receive 15% off invoice plus other benefits, which can offset a large portion of the upgrade cost.
• Schedule during standard hours when possible. Emergency utility coordination can add fees.
• Take advantage of the no‑charge annual electrical inspection to plan upgrades before they are urgent.

Preparing Your Home Before the Electricians Arrive

A little prep speeds up the day and keeps your project smooth.

• Clear a path of 3 feet in front of the existing panel and the planned panel location. This is required working clearance.
• Move cars out of the garage if the panel is there. We need room for ladders and materials.
• Unplug sensitive electronics. Your new whole‑home SPD protects the system, but it is smart to unplug TVs and computers during the outage.
• Refrigerators and freezers usually hold temperature during a normal outage window. Avoid opening doors and consider ice packs if the outage may be extended.

We will confirm the outage window, probable inspection time, and restore targets the day before the upgrade.

Common Myths About 200 Amp Upgrades

1. “I will use more electricity just because I have 200 amps.”
   • False. The service size is capacity, not usage. Your bills follow what you run, not the panel rating.
2. “A subpanel is the same as a service upgrade.”
   • Not always. A subpanel adds spaces but does not increase the main service rating. If you are at the limit, only a service upgrade raises capacity.
3. “My lights dim, so I need a bigger service.”
   • Maybe. Dimming can come from loose connections, weak breakers, or voltage drop. Our thermal imaging and tests find the true cause before we recommend a 200 amp upgrade.
4. “Surge protectors are optional.”
   • Current code requires a surge protective device at the dwelling service. It protects appliances and electronics from transients.

What Homeowners Are Saying

"We had a complete electrical panel relocate from inside to outside and the work was completed timely and very professionally. We also had some miscellaneous wiring cleaned up and everything looks great. Highly recommend 5th Generation and shout out to Xavier for providing detailed information and performing exceptional work."
–Panel Relocation Customer, DFW

"Outstanding customer service. I needed a three way switch replaced because I failed at replacing it myself, they were here the next day. I was impressed that they wore fancy coverings over there shoes. They even gave my electric panel a once over to check for deficiencies... one of my breakers are too large for my A/C compressor and overloading it."
–Safety Inspection Customer, DFW

"Eddie and Xavier came out less than 2 hours later, ran tests, diagnosed the problem... then they did an inspection of our entire home and left me a report on what looks good, the safety hazards & the areas of concern that they found (green, yellow and red, so easy to understand!)."
